Neuron 

Yeah, that new version fixed almost everything. My shammy is back to normal, my rogue is better at least in terms of action bars but all of the non-action bar types (status, menu, pet, etc?) seem to have reset so I'll just copy over my default profile and re-do that profile from scratch, no big deal.

Thanks for the quick fix!

That would make sense for the bag bar, that's probably where they are by default, although it doesn't seem to explain the non-interactive menu bar since I *do* have a menu bar on all my toons.

Anyway, at this point I'm in workaround mode so if you need anything else tested let me know. I'm done with progression play for this expansion so this would be the time for screwing around with things.

And full disclosure, I've deleted my cast bar as well. Doubt that's related, though.

I just added an edit to my last comment, logged into a different toon post-maintenance and it looks fine so far, I don't know how to explain what happened earlier but I'll keep testing.

EDIT: I've updated my previous comment since it may be class-specific (or at least how I set up the bars for him specifically), I have all classes in my mission table table rotation so I'll take a look at each and will update again if it's happening anywhere else.

EDIT2: Added other details below after trying to copy the rogue's profile on a warrior to see if it was profile- or class-specific.

EDIT3: Below, this is becoming hard to read, I'll do further edits below as necessary.

The only consistent issue I'm seeing so far is that my deleted bag bar is back, sort of... seems that what you did doesn't work properly if the bag bar had been deleted, it shows near the bottom centre of my screen but I can't interact with it, either the buttons or the bar, nor does it show up in my list of bars. I can't figure out how to get rid of it. For now I'll adjust the strata of my action bar so it doesn't show over actual buttons I want to push but I'd prefer it not be there at all.

(so, I have a saved profile that didn't have a bag bar, I updated Neuron, now I have an odd orphaned bag bar showing up that doesn't seem to do anything)

Aside from that, whatever you did with the borders for the menu bar aren't ideal either, I have mine set to be vertically oriented (2 columns) and the vertical spacing is larger than it was so it's unnecessarily tall. No change in horizontal spacing that I can see, it's just vertical.

When I copied the rogue profile to a warrior it gave a mixed result, the LUA errors didn't happen (so they appear to be class-specific) but the menu bar which is normally vertical and bottom-right of my screen was
just left of the odd non-interactive bag bar and was also non-interactive. Most of the other bars (status, zone, etc) had reset their positions and had no buttons on them, that isn't exactly what I was seeing on my rogue but it's equally bad.

In theory I could just create a fresh profile on my rogue to see what happens, I'm *assuming* it was just related to the update of the profile and it'd be fine if I created it from scratch with the new version but I'd prefer not to touch it until you have what you need. Let me know.

EDIT3: High strata worked to ensure the action button was on top of the bag bar, if that helps somehow.

Affected classes/specs (note - the menu bar also being non-interactive was also happening with the rogue, just didn't notice it previously), all have the same symptoms: Rogue (Assassination), Shaman (Elemental). Just the two in terms of the specs that I have set up. I can't think of anything those two specs have in common.

Unaffected classes/specs (aside from the bag bar showing up and non-interactive and the vertical menu bar spacing): Monk (Windwalker), Mage (Frost), DK (Blood), Priest (Shadow), Paladin (Protection), Hunter (Beastmaster), Demon Hunter (Vengeance), Druid (Balance), Warlock (Destruction), Warrior (Protection).

EDIT: I've only seen this on one toon so far, another has been fine (more or less). I've added the error I'm getting below the previous comment in case it's somehow useful, since I have copied profiles on all my toons I have no clue why one would be acting differently.

In live this basically broke everything for me so I'd suggest others not install, I don't know if it's recoverable by reverting versions, the server just went down so it'll be a bit before I can check.

I didn't document the specific LUA error (only had about 2 minutes before server down) but it was something about 'manacolor' to NIL and it was spamming every few seconds so whatever it was kept trying to heppen.

The in-game symptom was that my bag bar (which I had deleted previously, I don't use a bag bar) was back, my action bar location had been replaced by the menu bar, the Ach button from the menu bar was missing from that bar but showed up separately, and larger (same size as my action bar buttons) and all of my other bars had either moved (action bar up to the centre of the screen and had no buttons) or were just blank, with or without buttons (most didn't have buttons, I think the pet bar may have).

I'll edit this with additional details once the server is back up, I didn't see any sort of indication of maintenance in the BN client so I don't know what's going on. After I've documented the error I'll try reverting.

Here's the error, it's my rogue so maybe it's something related to a particular type of spell, macro or flyout that he uses but the other doesn't?

You're a saint as always! Thanks for getting this done for us. Anything specific you need us testing for you?

Thanks for the update!

How did you start? Whenever i think of starting i just get lost not knowing how to start at all.
